I've got a 97 3.4. It's loosing coolant and it seems to be getting worse. I've added almost 7 liters in the last 3 months.
I can smell coolant in the cab while driving so I suspected a bad heater core, but the floorboards are bone dry. Theres no visible leaks. oil looks fine.
I pulled the codes and its not missing (only code was intake air temp circuit). It dose idle rough on start up for a few seconds then its fine, and some white smoke as well.

OK so I just went out and started it up and it looks more like white smoke to me. it lingers in the air for a bit instead of dissipating right away like steam, and I managed to make a pretty big cloud from revving the engine. I hit the throttle a bunch of times while watching the coolant in the top of the rad and managed to squirt coolant right out of the rad. Would this happen normally or would that only be caused by pressure build up in the system from the compression in the cylinder backing up though the failed gasket? At this point I'm thinking I'll have to just take it to a shop.

Also I would have to wait for the funds to be able to pay for a HG job. Is there anything bad about putting in some stop-leak or some sort of product to buy me some time while I build up the funds?
